CVE-2020-6975Network attack vector

Authenticated malicious file upload via unrestricted types

Published Feb 12, 2020 · Updated Aug 4, 2024

Unrestricted file upload in Digi ConnectPort LTS 32 MEI firmware 1.4.3 allows remote authenticated users to upload malicious files. The web interface's upload feature accepts dangerous file types without restricting them, although public sources do not identify the handler or storage path. Administrative privileges and network access to the management interface are required, and the documented consequence is unauthorized file placement rather than code execution.
